Thinking in 3 directions

I'm working on an cut-away illustration/diagram of a 19th century brewery that used to stand on the Don River near Broadview Avenue. The building burned down in 1847, but the landscape was never redeveloped. From the brewer's diary (which he kept almost every day for many years) I can glean small references to the layout of the brewery, and its malt house, brew tower etc. In addition, beer enthusiasts everywhere have created a large body of educational material about how it might have functioned inside. From these three directions, I'm able to imagine what the brewery looked like, and how people worked inside of it. I'm visually reconstructing something that hasn't stood on that spot in over 150 years.
